AWS Certified SysOps Administrator – Associate (legacy) — Question 335

A user has launched an EC2 instance. The instance got terminated as soon as it was launched. Which of the below mentioned options is not a possible reason for this?

Answer options

• A. The user account has reached the maximum EC2 instance limit
• B. The snapshot is corrupt
• C. The AMI is missing. It is the required part
• D. The user account has reached the maximum volume limit

Correct answer: A

Explanation

If an account reaches its maximum EC2 instance limit, AWS prevents the launch entirely by returning an InstanceLimitExceeded error, meaning the instance never even starts. Conversely, issues like corrupt snapshots, missing AMIs, or reaching volume limits will allow the launch process to begin but cause the instance to terminate immediately after starting.
